Wedge Silica Refractories

Listing ID #5129304

silica bricks are made of quartz stone material, the content of sio2 is more than 96%. The nature and craft process of silica bricks are closely related to the crystal transformation of sio2. The density is an important quality indicator of silica bricks. The density of silica bricks should be below 2.38 g/cm 3. The quality of silica brick should be below 2.35 g/cm3.

silica bricks have the excellent ability to resist acid slag and acid solution erosion. besides, silica bricks have good high temperature strength, high refractoriness under load about 1640-1680°c, high softening point with temperature. What’s more, silica bricks are also featured with good heat conduction and the refractoriness is 1690~1730°c
